The economic crisis has coincided with historically high gold prices to boost the importance of so-called “cash for gold” businesses. Because the buyer usually has only a few minutes to estimate the value of gold items presented for sale, methods like touchstone analysis are often used: Although this test severely scratches the piece it is still not 100% reliable. The industry demands a precise, quick and foolproof method for testing gold content that is, above all, non-destructive.

Known for their resistance to oxidation and corrosion, Inconel alloys are often used in extreme environments subject to high heat and pressure. This is why Inconel coatings are often used in waste heat recovery boilers, which recycle the energy contained in hot exhausts given off by various manufacturing processes. However, to assure the functionality of the coating, a minimum thickness must be guaranteed, and thus, measured precisely.

In the manufacture of thin film solar panels or foils (e.g. CIS/CIGS, CdTe) it is crucial to maintain the specified limits of thickness and composition exactly, as this directly affects the efficiency of the panel. Only with a precise, fast and reliable inline measuring system can the production parameters be continuously monitored and, thus, the quality of the coating processes ensured.
